You considered the situation of moving a couch at a constant speed. You concluded that to move the couch at a constant speed, yo

Dmitry [639]

Answer:

The couch will remain stationary

Explanation:

Friction is the force that resist/opposes the motion. It is the force that has to e overcome before an object can move.

Since the frictional force of 50 N is required before the couch can move, applying 25 N can not overcome the frictional force of 50 N, so the couch will remain stationary.A force greater than 50 will be require to set the couch in motion

Describe the benefits and risks associated with nuclear energy.

Ulleksa [173]

Producing nuclear energy is far more environmentally friendly than burning fossil fuels. That is the main benefit.

The main risk is radiation. If the nuclear waste is not properly disposed of, it can leak radiation into the environment. Fortunately, this is not an issue since there are ways to deal with it. There is also the risk of a disaster like the Chernobyl incident, however that was mostly due to faulty reactor construction. However, reactors today are built to avoid such issues.

1) what is the potential energy at the end of the loop?

AlexFokin [52]

The potential energy at the end of the loop is equal to 0.3407 Joules.

Given the following data:

Mass of rock = 102.16 g to kg = 0.10216 kilogram.

Height of the loop = 34 cm to m = 0.34 meter.

Acceleration due to gravity = 9.8 $m/s^2$

<h3>What is potential energy?</h3>

Potential energy (P.E) refers to the energy that is possessed by an object due to its position (height) above planet Earth.

Mathematically, potential energy (P.E) is given by this formula;

$P.E = mgh$

Where:

m is the mass of an object.

g is the acceleration due to gravity.

h is the height of an object.

Substituting the given parameters into the formula, we have;

$P.E = 0.10216 \times 9.81 \times 0.34$

P.E = 0.3407 Joules.

<h3>What is kinetic energy?</h3>

Kinetic energy (K.E) refers to an energy that is possessed by a physical object due to its motion.

Mathematically, kinetic energy (K.E) is given by this formula;

$K.E = \frac{1}{2} MV^2$

Note: You'll have to calculate the velocity from the distance traveled by the car and photogate time in your experiment.

Based on the law of conservation of energy, we can deduce the following points:

Potential energy (P.E) is highest at the top of the loop while kinetic energy (K.E) is lowest.

Kinetic energy (K.E) is highest underneath the loop while potential energy (P.E) is lowest.

The ____ of emitted light depends directly on the energy between the two orbits and this determines the color of the light

Anna007 [38]

The frequency of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

<h3>What is light?</h3>

Light can be defined as a form of electromagnetic waves that does not require any medium for its propagation. This ultimately implies that, light is a form of wave that is generally referred to as a visual signal because it can be seen with the eyes.

According to the model of light wave, the frequency of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

In conlcusion, the frequency of emitted light is highly dependent on the energy between the two (2) orbits.
